Ben Affleck on Having More Kids: "Three Is Good! That's Enough!"

Three is the limit for BenAffleck! Talking to Extra at the UCLA School of Theater, Film and Television Film Festival on Thursday, June 13, the Argo director revealed he's done having children with wife Jennifer Garner. (The Daredevil costars, who got married in 2005, are parents to daughters Violet, 7, and, Seraphina, 4, and son Samuel, 15 months.)

"That's not going to happen," he said of having a fourth child with Garner, 41. "We're in a really good place. Three is good! That's enough!" (Affleck has a younger brother, actor CaseyAffleck. Garner, meanwhile, has two sisters: MelissaWylie and Kay Carpenter.)

At the same event, Affleck, 40, spoke to Us Weekly about his "sweet" children. "Raising kids is the greatest thing I think a person, or at least I, could ever do in my life," he said. "I know what the best part of my life is and it's my kids and it doesn't mean there aren't other things that aren't great, but I know sort of what the center is."

The actor-turned-filmmaker added that it's important to have "a kind of balance" between his work and home lives. Though he's a dedicated father and husband, the humble star told Us he's not perfect. "[I'm] just figuring it out as it comes," he explained. "I certainly don't pretend to have all the answers."
